I'm not sure that even the "AI generated output is not copyrightable" stance will be maintained - as long as "AI generated output" becomes big business. Same way copyright was invented and Sonny-Bono-extended to the max as long as content became big business.

In the model's case, though, it's even easier why it could be copyrightable, as a "baked" model is still created by people fine-tuning it, setting parameters and hardcoded stuff, training it with this or that set and excluding other, and so on.

For example music composed and rendered as audio by generative algorithms (something which doesn't even need AI, just some rules and stohastic processes) has been created and copyrighted just fine for decades...
